What Makes Cypress's Water Unique?
Local geology and source profile
Cypress, California, in north Orange County adjacent to Los Angeles County — a diverse planned community known for its Korean-American and Japanese-American communities, the Cypress College, and the Los Alamitos Race Course and Training Center, a classic north Orange County suburban community at the LA–OC border — draws its municipal water supply from Metropolitan Water District (MWD) imports and Central Basin supplies via the City of Cypress Water Division. Water hardness in Cypress measures 74 mg/L — classified as moderately soft.
Cypress' moderately soft supply — among the softest in Orange County for an MWD-dependent community — reflects the city's advanced treatment and modern infrastructure. Cypress is a well-managed planned community (developed primarily in the 1960s–1970s) with a modern, maintained water distribution system. The City of Cypress Water Division applies advanced treatment processes to the MWD import and Central Basin supplies, dramatically reducing the MWD Colorado River hardness (270–310 mg/L). Cypress' distribution infrastructure — regularly upgraded and replaced in the modern post-war planned community mold — adds minimal accumulated hardness, producing the moderate 74 mg/L — soft for Orange County.
With hardness at 74 mg/L, Cypress residents enjoy moderately soft water for a Southern California community. City of Cypress Water Division consistently delivers water meeting all California SWRCB and EPA Safe Drinking Water Act requirements.
Geology & Source: Mixed supply from the Metropolitan Water District (MWD) import and the Central Basin Municipal Water District via the City of Cypress Water Division — the Orange County north Los Angeles–Orange County border Central Basin zone (MWD import + Central Basin aquifer); moderately soft supply at 74 mg/L — reflecting the Cypress water treatment and modern distribution infrastructure in the north Orange County zone.
